PETER JACOBSEN, 0F PERTH AMBOY, NEW JERSEY.

4 To all 'whom t mayconcem:

Be it known that I, PETER JAcosEN, a citizen of the'United `States, residingat lerth Amboy,- in the county ofv Middlesex and State of New Jersey, have invented certain new and useful Improvements in Seal-- ing Apparatus for Vrappers', of which the following is a specification.

The present invention appertams to 1mprovements in sealing devices for wrappers,

adequately controlling the heat in the chambers aforesaid, such means constituting valves for permitting escape of products of combustion from the heat supplying elements.

These and such other objects as may hereinafter appear are attained by the novel construction, combination, and arrangement of parts to be hereinafter specifically described and claimed.

Reference will Vnow be had'to the accompanying drawings forming a part of this specification, wherein:

` Figure l is a side elevation of an apparatus constructed in accordance with my invention. Fig. 2 is an end elevation of the same. Fig. 3 is a top plan view thereof, parts being broken away and shown in section to more clearly disclose the details of Fig. 4 is a transverse sectional View on the line 4 4 of Fig. 3. Fig. 5 is a transverse sectional view on the line 5 5 0f Fig. 3; and Fig. 6 is a horizontal sectional view on the line 6 6 of Fig. 1.

Throughout the following detail description, and on the several figures of the drawings, similar parts are referred to by like reference characters.

Specifically describing the invention and referring to the drawings, l designates a suitable support or table upon which is removably disposed the sealing apparatus comprising the essential features of my invention. This 'apparatus consists of hori- Specication of Letters Patent.

SEALING APPARATUS ron WRAP'PERS.

zontalsupporting members .2 and- 3, which y members Yare adapted to receive the articles to be operated upon and which members are also adjustable with relation to each other to accommodate articles of different sizes as will 'be hereinafter more particularly set forth.

' Thel members 2 and 3 may be of any de- I sired material such as wooden planks, the former relatively fixed, While the latter `is capable of adjustmenttoand from the member 2. The supporting section 2 is connected j Patented Oct. 5, 1915. Appuation med May 1071915, serialNo. 27,187. v

to spaced guide members 4 which are removably positioned transversely of the frame or table l hereinbefore mentioned. The sections 2 and 3 include corresponding lower elements 2', 3 extending beneath `the cross bars 4 and being secured to the respective sections 2 and 3 through the instrumentality of the spaced guides 5 arranged at each side of each of the transverse bars 4. Obviously the section 3 is adjustable laterally on the bars 4 withfrespect to the section 2, as when it is desired to operate upon bread or other wrapped articles of different lengths.

Projecting upwardly from the sections 2 and 3 are corresponding side members 6 between which the articles are moved in the process of sealing the wrappers. At the forward end of each of thesev side members is located a folding roller 7 said roller being positioned at an incline as best disclosed 1n Fig. l of the drawing. Arranged transversely of the sections 2 and 3, and secured iXedly to the former is an elongated heating chamber 8, provided with a heating plate or cover 9 which is preferably of aluminum or similar heat retaining material. This chamber, and its cover plate, of course, is of sufficient length to allow of the maximum adjustment of the section 3 and the compartment is arranged at a point intermediate the lengths of the said sections 2 and 3. At a convenient point directly beneath the chamber 8 is disposed a lamp or other suitable heat supplying membery 10 which is disposed upon a platform or support 11 suspended from the member 2 by means of the hanging wires 12. The lamp is provided with a chimney 13 having a sight window 14 at one side, which chimney communicates or eX- tends into the chamber 8 so as' to supply heat to said chamber for action upon the heating plate 9 thereof.

Adjacentto the outer end of the chamber 8 is provided an opening 15 through which the products of combustion from the lamp are permitted to escape. Cooperating with the opening '15 is a valve or closure means 16 which is designed to regulate the,

escape of the heat from the chamber 8 in an l. obvious manner, thereby controlling the temperature of' the heating plate 9. Each of the side members is similarly provided with a heating chaii'iber 17, said chambers having` heating plates 18 flush with the inner walls of the side members Vand located inadvance of the heating plate 9 for thechamber 8. A lamp 1S) carried upon a platform or support 2() suspended from the member 2 by the wires '21'supplies heat to one of the chambers 17 with which its chimney 22 comn'iiinicates and another lamp 23 similarly supported by a platform 24 suspended from the element 3 by vthe wires 25 supplies heat to the other side chamber 18. It will be noted by reference particularly to Fig. 4.. of

the drawing that the chambers 17 are of special construction in that each is provided with a delecting portion 26' adjacent to its top and slightly above a lateral opening 27.

v The opening 27 is provided with a closure member or valve 28 for regulating the operative area of said opening in a manner similar to that describedwith reference to the opening of the chamber 8. Obviously the heat from vtheflamps beneath the side cham- -bers will tend to remain in the compartments and to aEect the temperature of the heating plates 18 by reason of the deflecting portion 26 just described, the products of combustion and excess heat passing out through opening 27 located at a point-opposite the lowermost portion of the plates 18.

In the broader phases of the invention, it will be obvious that an effective control is provided by the use of heating instrumentalities of the character hereinbefore described, the lamps employed being capable of adjustment in the conventional manner so as to regulate the amount of heat which said lamp generates. In other words, to increase the heat the burner is turned up and to decrease it the burner is turned down, and independentof this adjustment the amount of heat whicli-is retained by the chambers is controlled by the Valves or slide members hereinbefore described which more or less regulate the operative area of the .openings in the respective heating chambers. rllhis affords a dual control which is independent with respect to each of the heating compartments.

The operation of the apparatus Will be readily understood though it may be mentioned that the bread or similar article is Wrapped with paraiiin or waxed paper at` the article with the heating plates 18 causes the paraflined edges or end surfaces ol the wrapper to adhere to each other and the further moveinent of the article along the supports 2 and 3 brings the bottom oi said ai'- ticle on to the heating plate 9 whereupon the edges of the wrapper are caused to adhere ina similar manner, effectively sealing the contents. l/Vhile under' ordinary conditions the sealing operation is carried out as above f 'f The apparatus comprehended by this inventioii is simple in structure and may readily be employed in all localities since it employs heating means of a very conventional type.

Slight changes may be made in the details of construction and arrangement of parts, without departing from the spirit of the in-. vention, and within the scope of the claims hereto appended.

Having thus described my invention, what 'I claim as new is:

,1. Sealing `apparatus for wrappers comprising a support, guide means for the wrapped articles carried by said support, heating means disposed in said support and guide means, and comprising chambers, one wall of each of which constituting a heaty. ing plate, means for supplying heat to the chambers, and means for regulating the amount of heat retained by said chambers, said means comprising a valved opening disposed adjacent to the -bottom of each chamber in the wall-thereof opposite to its heating plate.
